Abstract: PURPOSE:To increase a signal-to-noise ratio by a simple structure by providing two photovoltaic type semiconductor detectors having sensitive layers corresponding to the maximum range of beta-rays and characteristics reverse to each other so that currents generated by beta-rays cancel each other. CONSTITUTION:First and second photovoltaic semiconductor detectors 16 and 18 having sensitivities to beta-rays and formed with surface barriers are fixed together with both ohmic contact electrodes 17 and 17', respectively, in contact with each other. By making the thickness of a sensitive layer region 16 equal to a value corresponding to the maximum range of beta-rays and forming a barrier potential by an electrode 15, a photovoltaic type beta-ray detection is conducted. When beta- and gamma-rays are radiated from a radiation source 1, a current (Ibeta+Igamma) due to beta- and gamma-rays is generated in the detector 16 and a reverse current -Igamma of the same degree as the current generated in the detector 16 by gamma-rays is generated in the detector 18. Therefore, when the currents due to gamma-rays from both the detectors 16 and 18 are inputted to an amplifier at the same time, the currents generated by gamma-rays cancels each other and only a current generated by beta-rays can be measured.
